What is the Manufacturing process of the ERW Pipe in Saudi Arabia?

Electric Resistance Welded or an ERW pipe in Saudi Arabia are used on a larger scale. It’s the high-end strength of the pipe that makes it such a wide application. Many industries use ERW pipes for their various work applications, including oil, gas, water, and construction. The pipes are made from multiple types of steel, including stainless steel, carbon steel, and galvanized steel, which are renowned for their strength, durability, and resistance to corrosion. 

Steel pipe is manufactured by rolling a steel strip of desired width and then welding it longitudinally with the help of high-frequency electric resistance welding (ERW). The cross section of the ERW pipes can be kept in different modes, such as welded junction, square, or cylindrical closed end. The length and circumference of the pipes can be customized according to the requirements. One of the best things about the manufacturing of the ERW pipes is that there is no involvement of any filler metal, unlike any other traditional form of joining. It is the defining reason for its top-notch strength measure. 

Manufacturing Process of ERW Pipes in Saudi Arabia

The manufacturing of the ERW pipe in Saudi Arabia might seem to be a few steps and easy to perform. On the contrary, it needs highly equipped technology, expert involvement, various measures, and more. It can’t be made of any desired shape with any likable time of any frequency of the electric resistance welding. The following are the real steps involved in making an ERW pipe.:

1. Raw Material

The initial step is to finalize the raw material needed to manufacture the pipe. Most of the time, they are made up of steel coils, which can be hot-rolled, cold-rolled, or galvanized. Each varies from the others in terms of cost and strength. However, they deliver higher working features broadly.  

2. Cold Forming

Now, the second step involves shaping the steel into a cylindrical tube using forming rolls. The end of the tube was shaped in various ways as needed. It can be open, closed, thinner, or wider than a regular one to provide a suitable fit for other pipes. Furthermore, the process is done at room temperature. 

3. Quality Control

Now, the final steps of the entire process come into play: the quality checks. Precisely, it is a quality assessment of all the steps taken to build an ERW pipe in Saudi Arabia. From weld perfection to surface finish and correct diameter, to length and weight measurements, all are being checked.

4. Internal Bead Removal

In several cases, there is a need for the removal of the internal weld bead. It provides a smooth touch-up with strength from the inside out, using prepared pipes. However, it’s not necessary to do it; it’s the manufacturing supervisor's experts who decide which call to take. 

5. Finishing

It is the second-to-last step of the whole pipe manufacturing process. In conclusion, the cooling, rounding, and cutting of pipes into the desired length and diameter occur. The required shape and dimensions are predefined to ensure the process runs smoothly. 

6. Welding

Welding is performed with a high-frequency machine, which uses an electric current to the edge, resulting in the fusion of the two ends of the steel coil. As there is no filler metal used, there is a possibility of cracks or joint brokerage. 

Summing It Up!

With the rapid growth of defining infrastructure, the need for ERW pipe in Saudi Arabia has increased exponentially. In infrastructure, there are various working spaces where the need for steel ERW pipes is required on a larger scale, especially in government-based projects. The development of the flyover, roads, buildings, etc, all required vast quantities of the ERW pipes.  The hosting of the FIFA World Cup, a global event, has given the Kingdom of Saudi Arabia its most significant boost in development speed. 

By meeting all the necessary standards, such as those set by the Saudi Arabian Standards Organization (SASO), for ERW pipe quality and safety, Matco Industry has established itself as the premier ERW pipe manufacturing company in Saudi Arabia. From the oil to the pharma industry and the chemical industry to the agricultural sector and much more, they make pipes of all types with different dimensions.
